We systematically study the AFM order of Fe1 zigzag chains and spin-flop ofexcess Fe2 under high magnetic field H through the susceptibility,magnetoresistance (MR), Hall effect and specific heat measurements inhigh-quality single crystal TaFe$_{1+y}$Te$_3$. These properties suggest thatthe high temperature AFM transition of the TaFeTe$_3$ layers should be aSDW-type AFM order. Below T$_N$, Fe1 antiferromangetic zigzag chains willinduce a inner magnetic field \textbf{H$_{int}$} to interstitial Fe2 and leadFe2 also forms an AFM alignment, in which the magnetic coupling strengthbetween Fe1 and Fe2 is enhanced by decreasing temperature. On the other hand,the external magnetic field \textbf{H$_{ext}$} inclines to tune interstitialFe2 to form FM alignment along \textbf{H$_{ext}$}. When \textbf{H$_{ext}$}arrives at the "coercive" field H$_C$, which is able to break the couplingbetween Fe1 and Fe2, these interstitial Fe2 atoms take a spin-flop from AFM toFM alignment. The local moment of Fe2 is about 4 $\mu_{\textrm{B}}$/Fe. Fromlow field ($<$H$_C$) AFM to high field ($>$H$_C$) FM for Fe2, it also inducessharp drop on resistivity and an anomalous Hall effect. The possible magneticstructure of TaFe$_{1+y}$Te$_3$ is proposed from the susceptibility and MR. Theproperties related to the spin-flop of Fe2 supply a good opportunity to studythe coupling between Fe1 and Fe2 in these TaFe$_{1+y}$Te$_3$ or Fe$_{1+y}$Tewith interstitial Fe2 compounds.
